There are three areas of enhancement to Lucid Puppy 5.1.1. One, it is built with the Woof (Puppy Build System) released on August 22. This has a number of enhancements over the July 10 version used in LP 5.1, including: transmit and receive cumulative totals in the network tray icon, refinements to Smbclinet and smbexplorer, and more support for dial-up modems. Two, the default internal browser has been changed to a splendidly small version of Midori built by Puppy’s technosaurus. Three, there are a number of bugfixes included from Instant Update 003 (for 5.1): provides libjpeg7, laptop function keys, configures Sylpheed email, fixes USB bootflash, links fsck, Arabic and Hebrew fonts, links to libfaad and libx264 for xfce, browser link to Lupu News Release info

Is Puppy Lucid 5.1 based on Ubuntu?

No.
Puppy is his own dog
We have a 'woof' building system
that allows us to build Puppy from the kernel
and binaries of other distros (pre compiled programs and libraries)
Puppy can be built from Ubuntu, Debian, Slackware, Arch and t2
with unique Puppy scripts, wizards and optimisation.

Does Puppy Lucid 5.1 use some Ubuntu files?

Yes indeed.
Puppy uses his own packaging systems (quickpet and pet)
Configuration and programs are Puppy specific
Lucid adds the tested efforts of some popular Ubuntu binaries.

How should Puppy Lucid be run?

Any which way you like
Once in memory, Puppy is fast whatever the method.
Run from DVD, CD, USB keydrive, SD, Hard Drive
or even in multi-session self auditing format
(files and updates saved on CD or DVD)
